C# - Retrieve The Name Of The Attribute Dynamically Without Specifying The Name Of The Attribute?
Aug 13, 2010I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD")
join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT")
on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT")
select new
{
SlotName = (string)SLT.Attribute("NAME").Value,
SlotValue = (string)SLT.Attribute("NAME").Value
};
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?
C# - Using A Resource As An Attribute To A HTML Element?
May 11, 2010I would like to have this piece of code in my .aspx file:
<input class="ms-ButtonHeightWidth" type="button" name="BtnOK" id="Button2"
value="Close"
onclick="javascript:HandleOKButtonClick()"
accesskey="<%$Resources:wss,okbutton_accesskey%>" />
Unfortunately, ASP.net doesn't seem to like that:
An error occurred during the processing of /_layouts/MyPage/Info.aspx. Literal expressions like '<%$Resources:wss,okbutton_accesskey%>' are not allowed. Use <asp:Literal runat="server" Text="<%$Resources:wss,okbutton_accesskey%>" /> instead
That doesn't work in this situation as that would mean nesting the Literal between the quotes of the accesskey attribute, which causes a "The tag contains duplicate 'ID' attributes" error.
Is there a way to use a string from a resource without having to change the input to an asp:Button? I guess there has to be a way using <%=, but I don't know how I would address the resource itself?

MVC Reading An Element's Custom Html Attribute When Submitting?
Nov 13, 2010I'm new to ASP.NET and MVC in particular. Now, I'm trying to understand if I can easily get values of custom attributes of submitted data. For example, When writing something like this inside a form (which works and posts and I can get the checkbox value) <%= Html.CheckBox("cb1", new { listen = "listen:6" }) %> Can I get the value of "listen" directly or do I need JS? (I know I can just use hidden fields, but I'm I'm asking anyway)

Get The Value Of An XML Element Using Linq Even When Empty?
May 13, 2010I am using ASP.NET in VB.
I have an XML document which contains all the details of staff in my company...
<staff>
<staffName>Test Staff</staffName>
<staffTitle>Slave</staffTitle>
<staffDepartmentName>Finance</staffDepartmentName>
<staffOffice>London</staffOffice>
<staffEmail>t.staff@company.co.uk</staffEmail>
<staffPhone>0207 123 456</staffPhone>
<staffNotes>Working hours Mon to Thurs 9.15 - 5.15</staffNotes>
<staffBio></staffBio>
</staff>
As you can see, some nodes do not always contain data for ever member of staff; only Directors have biographies.
I access the values like this...
For Each staff In ( _
From matches In myXMLFile.Descendants("staff").Descendants("staffName") _
Where matches.Nodes(0).ToString.ToLower.Contains(LCase(search)) _
Order By matches.Value _
Select matches)......
Once it gets to staffBio I get an error saying "Object reference not set to an instance of an object." obviously because that node does not exist.
My question is how can I assign the value to a variable even when it is empty without having to do a conditional check before each assignment?
